Vortex hunters are mysterious humanoid creatures from the Astral Plane. They are bizarre in that poisons seem to do nothing, they shrug off heat and cold like it wasn't there, and none have ever been observed eating, or drinking. They have been observed performing a kind of sleep, comparable to the Trance of an elf in that they never do it for longer than 4 hours, yet they seem just as well rested as a human after 8 hours of rest.
